Hey,

I was capped at 300kb/s until I put this in my config:

net {
    sndbuf-size       512k;
    max-buffers      20480;
    max-epoch-size   16384;
    unplug-watermark 20480;

 }

Good luck

Digi,

Thanks for advance again, but I've already tried this. I'm still pegged
at 2MB/s. I've exhausted IRC any google searches involving DRBD slow
sync. I'm really contemplating rebuilding the machine with a RAID 10 to
enhance performance but I still do not know if this is going to resolve
the issue, any thoughts about this? Thanks in advance.

Best Regards,

Dan Lavu

Digi,

I tried what you suggested, and set the syncer rate to 30M but I'm
still
not syncing past 2MB/s. Do you have any other ideas?

Read this:

http://www.drbd.org/users-guide-emb/s-configure-syncer-rate.html

In short, you should be able to issue a command similar to this:

drbdsetup /dev/drbdo syncer -r 40M

When done, issue this to revert to the drbd.conf settings;

drbdadm adjust r0
